Hyperstimulation during fetal heart rate (FHR) monitoring occurs when a deceleration in the FHR accompanies a contraction lasting greater than 90 seconds or contractions more frequent than every 2 minutes. A posthyperstimulation contraction stress test (CST) was performed, and if it was reactive negative, the next day's test was evaluated. On the next day, 170/250 (68%) of the tests were reactive negative, 33/200 (13%) of the patients underwent labor induction, 28/250 (11%) of the tests had hyperstimulation patterns again, and 19/250 (8%) of the tests were reactive equivocal; there were no positive tests. In this series of 250 repeat tests there were no adverse outcomes in patients who had a reactive negative CST after a hyperstimulation pattern, suggesting that the second test can be performed in a week rather than in a day.
